SPECIFICATION. forming part of Letters Eatent No. 727,161, dated Fey 5, 1903.

Application filed January 5, 1903.

To all whom, it may concern:

Beit known that I, THEoDoR II. J. LEcK- BAND, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Apparatus for Oarhureting Air, of which the following is a specification.

My object is to provide improved means for controlling air and oil in a carbureter as required to regulate the quality and quantity of gas produced at different times for streets, a, building, or collection of buildings for lightineand heating purposes.

My invention consists in the construction, arrangement, and combination of elements and subcombinations,as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in Which- Figure 1 is a. side elevation of the apparatus, partly in section, showing the relative positions of all the operative parts Fig. 2 is an enlarged sectional view of automatic air and oil feeding mechanism for regulating the quality and quantity of gas produced at different times to supply variating demands. Fig. 3 is an enlarged sectional view that shows the construction and combination of a valve and a lever adapted to operate automatically in,the feed mechanism.

The numeral '10 designates the bottom of a water-chamber adapted for submerging the main portions of the carburetor vessels, and 12 represents a floor fixed over the waterchamber. A double-walled tank 13 is fitted and fixed in an opening in the floor 12 and suspendedin the chamber 10, and a bell 14 fittedin the tank and provided with a plurality of antifriction-rollers 15 on its exterior to contact with the interior of the outer wall of the tank to aid in facilitating the up and down motions of the bell and to maintain it perpendicular.

An air-mixer in the form of a'perforated plate 16 is fitted in the tank 10 and tea tube 17, fixed to the bottom of the tank, and a frame 18, made of metal rods, fixed to the top of the plate, so that the plate can be raised and lowered by means of a lever 19, futamazed to the bottom of the tank and provided with a rod 20 at its free end, that is adiuatably connected with the floor 12 by means Serial-N0.137,978. (N0 model.)

0f teeth adapted to engage the floor or in any suitable way, as required, for retaining the plate at diifcrent points of elevation relative to oil'in the tank and the quality of gas to be produced.

A pipe 21 is connected with an air-pump 22 and a, branch pipe 23 extended therefrom through the bottom of the tank 1 to near its open top and terminates in a lateral extension 24, to which extension are fixed a plurality of tubes 25 to extend downward through the perforated plate 16, required,

to discharge air intothe oil below the mixerplate 1o.

An oil-tank is connected withantoinatic feed mechanism as follows: A pipe 27, open at its bottom, is lixed in the top of the oiltank to extend down to near the bottom of the tank and extended upward and arched at its top, and automatic feed-regulating mechanism inelosed in tubes connected with its end by means of a T-couplinp 28, as shown in Fig. .2. A glass tube or sight-feed 29 is connected with the pipe 27 above the coupling 28,515 shown in 1. A chamber 30 for a weight has air-tight connection with one end of the T-eonpling, a pipe 31 with the other end of the same coupling", as shown in Fig. 3, or in any suitable way, as required, for inclosing a lever 32, connecting a weight 33 with one end of the lever and a rod 34 with its other end. A tube 35 is connected with the lower end of the tube 27 by means of a union 36 and with the i couplizng 28, as shown in Fig. 2, or in any suitable way anda Valve'seat 37, fixed to its lower end and Within said coupling, and a valve 38, titted, to said seat and provided with a stem 39, that extends up through a bore in the seat and through an arched bearer 40, fitted in the tube 35, to retain the valvestem perpendicular and to restrict the downward motions of the valve by means of a nut 41 on the end. of the ste n1. ihe rod 34: has a plurality of notches at its upper end portion, and the long arm of the lever 32 has a SiilQlG notch that admits the narrowed portions of the notched rod, as required, to adjustably connect the notched rod with the lever, and a ieaf-spring fl, fixed to the lever, normally engages the rod 34, as required, to retain the rod connected. with ers is 121m;

4 pipe 66, that lies :i'ralve n. A sefetywalre the lever. An tsnlcEB is connected with the lower end of the pige 31 and with the bottom of he carbureter-teo k 13 by :1 tube 41'. To the bottom of the rod 34 is attached a float e5, rims will by ine rise and fall of oil in the will" 43 and 13 actuate the lever 33', as require 0 open and ciose the valveiBS, by means of ion the needed supply of oil is i'ed into said tanks sntomeiicaily. Valves 4:6 and 47 are connecied with the sight-feed 39 for closing eomrnnnicarioc therewith, and a valve 48, cen'necieii with the pipe 27, be closed to stop ihe iiew of oil downward and iuro iiie tank whenever desired.

A tuoe 4-9 is fixed o ihe lower portion of the tank 43 and extended into the botioxn of the carburetor-i k 13 to clrew water from the carlmreber L" into iiie air-eight tank 43 and provided wife valve a, naviogestcro i) for operating the valve. The pipe is is ziiso provided Wibn a valve 0 and stem (Z, projected upward therefrom, f closing communication beiweec ilie Senl i0 and A water-Light drip-oi l oer 50 is connected wiili the lower end of the robe 23 and tube 5* enteniied into said chamber and provided Wliil a removable cap 52, so that Water sconmiilsted in the chamber may be discharged iiiercirom by removing the cap and forcing air inso the chamber. 2* corresponding drip chamber is ccnnec in iiie pipe sewer extends m Willcii e cell 1 emi tank 18 to con '1 gas required to bnrn-= in buildings 0* sireeis, and a pipe cm "rested. iii: said chamber and provided wiiii a removable cap as means for removing WPLiQl and oil ilmimayget herin said chamber by forcing siricto 119 chamber.

A pipe 57 is connected with the top of the tank and has a coupling 58 fixed to its top. A glass tube 59, provided with a scale, is fixed on top of said coupling, e115 pipe 60 ext-ended from the same cocplin to the pipe iiiend pipe 61 is fixed :0 other side of said coupling and connectei. will: the pipe 21.
